I don't know where all the high reviews come from on this app, but they are clearly looking at a different app than me, the description stays you can look up conditions by typing in the problem, well I did that and it took me to the different conditions, but not to what I asked for, there's plenty of conditions in the app, but to find what you want, if your lucky it will be in the beginning of the alphabet, if not, you have to thumb down through hundreds of different conditions.

Thank you for your feedback. We've recently added a full-text search feature that allows you to directly find specific conditions. You can now enter your query, and the app will provide relevant results. We hope this improvement enhances your experience, and we appreciate your input as we continue to refine the app.

I just like the details the application delves in to explain the various conditions/diseases that even the common person can understand. Great application...more so that it keeps on giving "offline" feeds.
